IMPROVEMENT IN PRINTINGePRESSES.

Specification forming part of Letters Patent No. v41,84 l, (lated March 8, 1864.

To all whom. it may concern Be it known that I, GriiioRGrIi:v P. GORDON, of Brooklyn, Kings county, in the State of N ew York, have invented, made, and-applied to use certain new and useful Improvements in the Construction and4 Operation of Printing- Presses; and I do declare that the following is a full, clear, and correct description of my invention,referenee being had to the aecompanying drawings, making part of this speciiication, and to the letters of reference marked thereon, in whichy Figure 1 is a side elevation of myimproved printing-press; Fig. 2, a front elevation of the,

same; Fig. 3, a longitudinal sectional viewof the same; Fig. 4, a detached view of the cylinder or segment of a cylinder employed, showing the .nippers in theact of takingthe sheet from ,the feed-table; Fig. 5, a detached view of the cylinder or segment of a cylinder employed,- fshowing the tympan-holders and their mode of attachment; Fig. 6, a detached section of a :front View of my improved printing-press Fig. 7, a detached view of the cam in the blank Y' and of the eccentric 1'.

In theIdra-win gs like parts of the invention are designated by the same letters of reference.

The nature of my inventionr consists,- first, in taking the unprinted sheet from the feedtable, presenting 'it properly to the type for the reception of the impression, relieving' it from 'such impression, and .carrying it to and depositing it upon the pile-table by the use of reciprocating automatic nippers,whether conY structed and yoperated vin thel precise manner hereinafter shown or in an equivalent way to produce a like result; second, in combining said reciprocating automatic nippers witha cylinder or segment of a cylinder which shall have a part rotary with a return movement; third, in givinga reciprocating motion to the bed by and thrgigh the reciprocating motion of the cylinder` or segment of a cylinder 5 fourth, in the use or employment of the nippertrip'and the nipper-guide, in combination with the reciprocating bed and the reciprocating nippers, and in combining all of these with the cy-lindert or segment of a'cylinder which has a part rotary with a return movement;

fifth, in combining the tympan-sheet holders with the cylinder or segment of a cylinder for the purpose hereinafter shown; sixth, in the use or employmentof rotating reciprocating* nippers to pile the sheet, (heretofore patented l y`mc,) in combination with a cylinder or sega cylinder, substantially as hereinafter described.

I'Io enable those skilled in the art to make and use my invention, I will speak of its construction and operation.

A A show the frame for supporting the 4operating parts of my' improved printing-press.

B shows ways'upon the inside of said frame AA, upon which ways B the bed G travels to and from the impression.

C shows the, bed of my improved printingpress, in which bed C the form or types are placed. This bed C is provided with the rack D, gearing into the segment-gear Eupen the cylinder or segment of a cylinder F.

F shows a cylinder or segment ot' a cylinder hung upon the shaft G, and provided with the segment-gear E, gearing into the rack D upon the bedl C. This cylinder or segment of a cylinder F is -also provided with the tympanholders Il and H,attached. to the supports I' edge of the cylinder or segment of a cylinder.` The inside of the cylinder or segment ofV a cylinder is planed true to harmonize withl the ,gripping-edge of the tympanlholders, which,

when shut down agaillstlthe segment of a cylinder, insures the retention ofthe tympansheet. v f

J- shows the nipper-arms attached to the supports I, by which nipper-arms J and the rod K are supported Aand carried.

a and a2 show the sheet-taking nippers,

A -the upper nippers being designated by-ay and the lower nippers by a2. Both the upper, a.,

and the lower nippers, a2, are hinged or swiveled upon the rod Kr b is a spring wound upon the rod K, one end of which spring b is fastened iirmly in the upper nppers, a., while its other end is fastened in the lower nippers, a2, which spring serves to close and hold together the nippers c and a2 in taking the sheet from the stationary feedtable W.

cis a spiral spring placed upon the rod K for the purpose of turning the nippers a and a2 down to their proper position.v

d is a short eccentric-shaft held ina journal-box, e, firmly attached, upon the rod K. This short eccentric-shaft is provided at one end with an eccentric, and at its other end is attachfd the crank-arm f with the roller g. The eccentric plays freely between the nippers a and a2,- properly fitted for such purpose. The crank arm f, with its roller g, is operated by the trip V, and also by the stationary' trip V2, as described, and aids in opening and closing the nippers a. and a2. At the opposite end ot' the rod K is attached the crank-arm l, with its roller in, which crankarm l, through its roller m, impinges upon the nippcr-gnide z and nipper rod holder Y, to aid in opening and closing the nippcrs a and ai.

L shows a frame attached to the back of the press for supporting the inking-rollers n,which hiking-rollers 'n are inserted in the slots in the frame L.

0 is a shield, placed directly over the inking-rollers n, the front portion, o, of which shield O is properly curved and serves to prevent the printed sheet in its transit from the point of impression to the pile-board X from coming in contact with the inking-rollers n.

P shows the drivin g-shatt of the press, having keyed upon one end the cog-wheel Q, and upon its opposite end the surface cam 1t.

S shows a crank-arm keyed upon the shaft G. This crank-arm S and cog-wheel Q form cranks to operate the connection T, attached to them, as shown.

U is a bent lever operated by the surface cam R, to the upper end of which bent lever U the trip V, for opening and closing the nippers a and a2 upon therod K, when taking a sheet from the feed table W, is attached.

p is a spiral spring attached to the bent lever U and the frame A, which spriu g p serves to keep the lower end of the bent lever U always against the surface cam R.

W is the feed-table, upon which the sheet to be printed is laid preparatory to its being taken therefrom by the nippers a and a2 upon the rod K.

X shows the pile table, placed above the feed-table W, upon which pile-table are the iinger sheet-stops g q.

Upon the shaft P is placed the blank Y', provided with a cam.

Z is a crank-arm provided with a stud and roller, z', playing in the cam upon the blank Y.

r are eccentrics hung upon the shaft S', which eccentrics r' 'bear directly upon the under-side of the ways B, upon which ways B, the bed C-travels to and from the impression.

t is a cam placed upon the'inner side of the frame A A,i`n which cam t the stud and roller u upon the crank-arm v plays freely. The

`opposite end of this crank-arm 'u has attached to it the stud and roller w, playing in the slot w 'in the nipper-'arln J.

Suitable means for supplylngink tothe hiking-rollers a may be attached to the press.

Y isthe nipper-rod holder attached to the feed-table W.

z is a guide attached to the segment-gear E, for the purpose of elevating or depressing the nippers a and a2, through the crank-arm l and roller m, attached to the rod K and bearing upon the guide z.

Operation: We will suppose the tympansheet to have been placed upon the cylinder or segment of a cylinder, the form or types to have been placed upon the bed, and the sheet t0 have been laid upon the feed table preparat )ry to its being taken therefrom by the nippers. Motion being communicated to the press, the surface lcam R upon the shaft P, through the roller 3 and the bent lever U, commences to throw back the trip V, upon which trip V rests the crank-armf, with its roller g. As'the trip V continues its backward movement or is withdrawn from supporting the crank-arm f and its roller g, the spiral spring b closes the jaws of the nippers a and a2, which nippers a and a2 grip the sheet. The cylinder or segment of a cylinder F, operated Y-by the cranks S and Q, through the connection T, how begins its backward movement, drawing with it the bed C by means ofv the segment-gear E, gearing into the rack D upon the bed (J. As the cylinder or segment of a cylinder F progresses in its backward movement, the nippers a and a2, attached as shown, draw the sheet from the feed-table W, and, moving with the cylinder or segment ot' a cylinder F, present it the sheet) to the typo for the purpose of receiving an impression, the rod K, upon which the nippers. a and a2 turn, being held in its stationary position upon the cylinder or segment of a cylinder F by means of the stud and roller u pla-ying in the cam t. The sheet having been presented to the form or types, the bed C and cylinder or segment ofa cylinder F continue their backward movement until an impression has been given. Upon the continued backwardV movement of the cylinder or segmentA of a cyli-nderand the bed, the nippers a and a2, operated through the crank-arm and roller u, playin ,f in the cam t, commence rising upward and to'ward'the pile-table X, the nippers al and a2 being kept in the required position by the guide z upon the segment-gear E, and upon the cylinder or segment of a cylinder, and the bed reaching the terminusof their transit, the crank-arm f stationary trip V2, the nippel-'sa` and wuare opened, and by the aid of the finger: sheetstops@ q the sheet is piled' upon the pile-table X. During this backward movement of the bed the form, passing under the roller-frame L, in which are placed the rollers n, has re- AAA, .a v l first, .they open; second, they clo ceived its ink. When the cylinder or segmentof a cylinder has reached the terminus of its transit, it then commences its return or foravard movement, carrying with it thebed, and as this forward movement continues the eccentries r, operated by the cam in the blank Y upon the shaft P, are thrown out of the straight line occupied by them during the backward movement of the cylinder or segment ot' a cylinder and the bed, and the ways B vibrate with the bed C away from the cylinder or segment of a cylinder to avoid giving an impression upon the forward or return movement ofthe cylinder or segment ot' a cylinder and the bed. The cylinder or segment of a cylinder and "the bed continue their forward movement until the eranlcarm fand its roller g impinge upon the trip V to open the nippers a and e2 to take the succeeding sheet from the feed-table W, and the eccentrics r, opera-ted by theveam in the blank Y upon the shaft I), are thrown back (after the cylinder or segment of a cylinder and the bed have passed the point of impression) to the position occupied by them during the backward movement of the cylinder or segment of a cylinder and the bed, and the operation first described is repeated.

I would call particular attention tothe feature hereinafter claimed-namely, thc-reciproeating automatic nippers or nippers having a forward and backward movement as well as an independent movement in themselves. The offices or duties of these nippers are, upon and take' the unprinted sheet from the feed-table; third, they present the sheet properly to the type; fourth, they carry such sheet in harmony with the movement of the cylinder or segment of a cylinder during the giving of an impression .5 iifth, they relieve the sheet from the form or types; sixth, they move, after' an impression has been given, independently, and with a quicker motion than that of the cylinder or segment of a cylinder, to the pile-table with the printed sheet; seventh, they there open and pile the printed sheet; eight-h, they have a return movement or reciprocate to the feed-table to take the succeeding sheet. I have devised many ways to accomplish all of this by the use of reciprocating automatic nippers, and I deem it unimportant vwhether such nippers shall be constructed precisely vas shown, so long as a reciprocating motion shall be imparted to them for the pur poses I have fully described. i

I herein show but one ofthe many recipro eating movements I have tried, and I have chosen this method ofthe many, as it enables me to pile the sheet, printed side up, in the best possible position for the operator to see at once any imperfection that may exist.

`Une purpose above described-that of piling the sheet with reciprocating nippers--I have heretofore patented, but 4this was the the cylinder or segment of a cylinder.

sole duty of such ni ppers. This patent bears date November 16, 1858, and I claim the use of rotating reciprocating` nippers for such purpose, when used either separately or in combination. with a rotating reciprocating fly. These nippers were used for taking the sheet from a stationary platen after the impression had been given. In my present application I use the-sc pilingnippers in combination with the cylinder or segment of a cylinder and moving with and by the motion impartedto The novelty, utility, simplicity, and effectiveness of this combination will readily be seen.

In my patent of July 5, 1859, I claim, by use of automatic grippers, piling the sheets directly before orin frontof and under the eye of the operator, so that hemay at once detect any imperfection in the impression. This again wasused upon a press employing a bed and platen. I now claim thus piling the sheetin combination with a cylinder or segment of a cylinder, which is a feature of great importance in a eylinder-prcss-is also new and eX- eeedingly useful.

Ilaving thus described my invention, what l' cla-im therein as new, anddesire to secure by Letters Patent, is

1. Taking the unprinted sheet from the feed table, presenting it properly to the type for the reception of the impression, relieving it from such impression, and carryingit to and depositing it upon the pile-table, by the use of one and the saine set of reciprocating au-V tomatic-nippers, whether constructed and operated inthe precise manner shown or in some equivalent vway to produce a like result..

2. The combination of said reciprocating automatic nippers with a cylinder or segment of a cylinder' which shall have a part rotary with a return movement.

3. The nipper-trip V and the nipper-guide z, iu combination with the reciprocating bed and the reciprocatingnippers, and these in combination with the vcylinder or segment of a cylinder which shall have a part rotary with a return movement.

4. I he combination of the tympan-sheet holders with the cylinder orsegment of a cylinder, for the purpose shown.l

5. Rotating reciprocating nippers to pile the sheet, (heretofore patented b y me,) when combined with a cylinder or segment of a cylinder operating substantially as shown.

6. The piling the printed sheet-s by the use of one and the same set of reciprocating auf vtomatic nippers directly before or in front of and under the eye of the operator, so that he may at once detect anyv imperfection in the impression, (as heretofore patented by me,) when combined with a cylinder or segment of a cylinder, substantially, as described.
